[erlang-questions] Gen supervisor query...

Hi all,

I have a simple supervisor setup which is watching two worker processes.

Now I have created the init method as such:

init(Args) ->

    [{port,Port},{maxconns, MaxConnections},{sockethandlermod, SocketHandlerMod}] = Args,

    Registered = registered(),

    case lists:any(fun(X) -> X =:= ?CONNCOUNTER end, Registered) of

        true ->

            error_logger:info_msg("TCP connection monitor (~p) already registered...SKIPPING~n",[?CONNCOUNTER]);

        false ->

            register(?CONNCOUNTER, spawn(fun() -> counter(0, MaxConnections) end)),

            error_logger:info_msg("TCP server <~p> started TCP connection monitor.~n", [self()])


GenTcpServer1 = {'GenTcpServer1',{generic_tcp_server,start_link,[Port,SocketHandlerMod]},permanent,2000,worker,[generic_tcp_server]},

GenTcpServer2 = {'GenTcpServer2',{generic_tcp_server,start_link,[Port,SocketHandlerMod]},permanent,2000,worker,[generic_tcp_server]},

{ok,{{one_for_one,0,1}, [GenTcpServer1, GenTcpServer2]}}.

Nothing fancy going on there - I would expect this supervisor to start both GenTcpServer1 AND GenTcpServer2 given two speca have been returned?

For some reason it is only starting one when I look in appmon etc.

Any thoughts?

Many Thanks,
